Trial summary

Liver malignant tumor, including liver cancer and liver metastasis, is common in China [1]. Previous studies have shown that cyber-knife stereotactic radiotherapy is effective and safe for locally advanced liver malignancies with improved local tumor control [2]. Read more about this study

About this study

Liver malignant tumor, including liver cancer and liver metastasis, is common in China [1]. Previous studies have shown that cyber-knife stereotactic radiotherapy is effective and safe for locally advanced liver malignancies with improved local tumor control [2]. Real-time tumor tracking in cyber-knife stereotactic radiotherapy is currently used as tumors have respiratory movements [3]. At present, fiducial marker is used to realize the real-time track of tumor [4, 5]. However, the fiducial marker are likely to displacement usually within 7 days after implantation [4, 6, 7]. Therefore, simulated CT are delayed 7 days before the fiducial marker stabilization and significantly extend the radiotherapy planning process, increase the risk of tumor progression. As far as we know, there is no prospective study on the specific displacement distance and duration before the fiducial marker stabilization after implantation. Therefore, the purpose of this study was to study the displacement distance and stabilization time before stereotactic radiotherapy for liver malignant tumors guided by 3D printing template-assisted CT.

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Cancer, run by Peking University Third Hospital at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 18 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Displacement distance (time frame: Within 1 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2023.
